This appears throughout the app, the worrying thing is that we're unable to send notification emails, test email fails with:

An error occurred while sending mail ({{value}})

Setup details:

Using Redmine 1.1.0, with Postgres 8.4 on a Ubuntu x86_64 (VMWare) after generating an empty dB.

Any advice gratefully received as I pushed this into production thinking this issue wasn't that serious and didn't test the email notification first :-/
